A long winded speech about nothing, usually spoken by one of the varieties of Jonathan's (Johnathon, Johnathan). Almost always brought on by incredible amounts of liquor, this explanation about the fundamentals of nothing can take hours or even days to complete.

Wow, Jon was a drunk duck last night; he totally jonologued for a straight hour.

Tommy pulled a page out of J's book and jonologued about the importance of mushrooms the whole time. Fucking tool.
